Industrial thermocouple sensor

with ceramic protector

"CTPC" range


These industrial thermocouples are used in industrial processes where temperatures are very high. 

Thermocouples are protected by one or two ceramic protectors. The choice of the tube material depends on the temperature to be measured and on the working conditions.

Connection to the regulating system is made through a connecting head, generally in aluminium, equiped with a ceramic terminal block or a transmitter.

The most commonly used thermocouple types are K, N or R, S, B for higher temperatures.

Mechanical data

The thermocouples are generally protected by ceramic beads or tubes.

Accuracy

Accurary is defined by the thermocouple wires tolerances as per IEC 584
